What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time

• Continents are stationary and do not move

• The Earth is broken into lithospheric plates that move due to convection currents

• none of the above

What evidence did Wegener use in his theory?

• Continents and fossils fitting together/matching-up like puzzle pieces

• glacier scars and evidence from temperature

• mountain ranges and coal deposits line up across continents

• all of the above

Which of the following is evidence that supports continental drift?

• the presence of penguins at both the equator and Antarctica

• fossils of the same plant have been found on several continents

• the presence of glacial features in Antarctica

• the presence of volcanic rock in Antarctica

What was the name given to all the continents when they were joined as one super continent

• Glossopteris

• Eurasia

• Wegner Continent

• Pangea

What type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis?

• evidence from landforms

• evidence from fossils

• folk tales

• evidence from climate

What discovery caused scientists to rethink Wegener's continental drift theory?

• discovery of earthquake activity in California

• discovery of the ring of fire in the Pacific Ocean

• discovery of seafloor spreading in the Atlantic Ocean

• discovery of deep trenches off the coast of South America

The two mountain ranges that Wegener used as evidence of Continental Drift, because they fit together almost perfectly are...

• Appalachian and Rockies

• Rockies and Caledonian

• Appalachian and Caledonian

• Rockies and Swiss Alps

Which of the following states that parts of the Earth's crust slowly drift atop a liquid core?

• Theory of Evolution

• Heliocentric Theory

• Geocentric Theory

• Continental Drift Theory
